2010-01-08OMAP1 clock: remove __initdata from struct clk_functions to prevent crashCory Maccarrone
Commit 52650505fbf3a6ab851c801f54e73e76c55ab8da added an __initdata decoration to the structure containing the clk_enable and clk_disable functions. Once init data was freed, these pointers went to null, and the next enable or disable call caused the kernel to crash. This change removes this decoration.

2010-01-08OMAP1 clock: Add missing clocks for OMAP 7xxCory Maccarrone
This change adds in some missing clocks that were needed as a result of 526505... (OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c). Prior to this, it was just assumed that these clocks existed for all devices, and it was used directly instead of calling it out with a clock_get call or similar. So, not having the CK_7XX meant these clocks weren't being used anymore for omap 7xx devices, which broke things badly.

2010-01-08OMAP clock: remove incorrect EXPORT_SYMBOL()sPaul Walmsley
The only symbols that should be exported are symbols that are to be called from loadable kernel modules, e.g., device drivers. In the context of plat-omap/clock.c, these should only be the Linux clock interface symbols as defined by include/linux/clk.h. Core code doesn't need these symbols to be exported. Also, clean up an old comment while here. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2010-01-08OMAP2xxx IO mapping: mark DSP mappings as being 2420-onlyPaul Walmsley
Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430, we only map the IVA on OMAP2420. The memory mapping is not shared between OMAP2420 and OMAP2430, so it is inappropriate to label those macros as '24XX'; this patch changes them to '2420'.

pre-Pentium" This reverts commit ae1b22f6e46c03cede7cea234d0bf2253b4261cf. As Linus said in 982d007a6ee: "There was something really messy about cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it carefully."

2010-01-04sysfs: Add lockdep annotations for the sysfs active referenceEric W. Biederman
Holding locks over device_del -> kobject_del -> sysfs_deactivate can cause deadlocks if those same locks are grabbed in sysfs show or store methods. The I model s_active count + completion as a sleeping read/write lock. I describe to lockdep sysfs_get_active as a read_trylock, sysfs_put_active as a read_unlock, and sysfs_deactivate as a write_lock and write_unlock pair. This seems to capture the essence for purposes of finding deadlocks, and in my testing gives finds real issues and ignores non-issues. This brings us back to holding locks over kobject_del is a problem that ideally we should find a way of addressing, but at least lockdep can tell us about the problems instead of requiring developers to debug rare strange system deadlocks, that happen when sysfs files are removed while being written to.
